From 12edc9a8da2ec9b485d38b95663fb6df41a1ef55 Mon Sep 17 00:00:00 2001 From: Bo Liu Date: Tue, 6 Feb 2024 02:13:13 -0500 Subject: [PATCH] mfd: stpmic1: Convert to use maple tree register cache The maple tree register cache is based on a much more modern data structure than the rbtree cache and makes optimisation choices which are probably more appropriate for modern systems than those made by the rbtree cache.
